commons-logging issue (maybe JUnit-related)

[Mitch Gitman]

I'm trying to run some JUnit tests on an Axis client. My client class' constructor calls the default constructor for org.apache.axis.client.Service. This causes an exception to crop up:
java.lang.ExceptionInInitializerError
at org.apache.axis.client.Service.<init>(Service.java:108)
...
Caused by: org.apache.commons.logging.LogConfigurationException: ... org.apache.commons.logging.impl.Jdk14Logger does not implement Log
at org.apache.commons.logging.impl.LogFactoryImpl.newInstance(LogFactoryImpl.java:555)
...

Now, Jdk14Logger does implement Log; both are in commons-logging.jar. At first, I thought this was a simple classloading issue, that somehow an inconsistent version of the class or interface was being picked up. But after moving common-logging.jar to the head of my classpath list for invoking JUnit, I still got the error. And anyway, I don't see Jdk14Logger or Log elsewhere in the classpath.

I suspect this issue has something to do with JUnit, although I haven't a technical reason. Just, "Jdk14Logger does not implement Log" has made its way to the Cactus (JUnit for webapps) mailing list. Next, I'm going to try running my Axis client directly rather than through JUnit.
